Comparing the impacts of patch‐burn grazing on vegetation in two northern tallgrass prairies

open access: yesConservation Science and Practice, Volume 7, Issue 10, October 2025.
We evaluated two of the earliest and largest patch‐burn grazing projects in the eastern tallgrass prairie of Minnesota, an ecosystem that has undergone extensive fragmentation and invasion by non‐native species. Our results in grazed and ungrazed plots varied with differences in stocking rate and fire frequency.

ACYLATED (+)-CATECHIN GLYCOSIDES FROM ULMUS PUMILA L. GROWING IN EGYPT [PDF]

open access: yesAl-Azhar Journal of Pharmaceutical Sciences, 2012
Extensive isolation work on the n-BuOH-soluble fraction obtained from the stem and root barks of Ulmus pumila L. afforded five  compounds. Four were identified as (+)-catechin 1, (+)-catechin 7-O-gallate 2, (+)-catechin-5-O-b-D-apiofuranoside 3, and (+)-catechin-7-O-b-D-apiofuranoside 4. The structures of the remaining new compound was elucidated to be,
